EDIERGENCY CONVECTION HEATER.

Application filed February 16, 1928. Serial No. 254,718.

My invention relates particularly to improvements to the general class of emergency convection heaters which are attachable to and uicldy deuiountable from existing electrio xtures.

To the above ends, my invention consists of novel means for. adjustment whereby the flue surrounding my heating unit, which is prefcrably of any light transmitting material of low heat conductivity, and its adjuncts of my device may be moved in or outin relation to the face of the fixture on which it is to be mounted, thereby permitting the mounting of my device on any type of existing wall fixture regardless of the distance from the' ceiitei' of the socket or receptacle of the fixture to the "face of the fixture, a distance whichvaries from l ".to asmuch as 3". My invcntionfurt'her consists, ofj'novel means for rigidlyholdiin myfdevice in the desired position in the sqcietor receptacle to which it has-been attached. 1, My invention further 'consis ts' oi n'ovel means for rigidly holding the socket or .1"e= ceptacle, on which my device has been mount;- ed, in relation to its support, thereby relieying the socket or receptacle of.:ill. strain and removing alldang'er pt itsbregking away from its support onibase.

i i so My invention further {consists of noyel means for ventilating my heating unitcore, whereby I reduce the intensity,'of the h eat absorbed and retainedby. this-core irom the heating element which it supports, yvhichheat is destructive both to the core and to the socket to which the core is attached.

My invention further consists of snovel'de- Hector-reflector for deflectin the liot'air generated by the device in any ireotion desired, and for dili using the heat rays of the heating unit.

My invention further. consists ofnovel in sulating reflecting means for reflecting the heat rays thrown out by the device,- any direction desired, which also acts' to protect walls, furniture etc. from theseheat rays when the device is operated adjacent thereto.

My invent-ion further consists of novel means for adjusting the position of myflue and its holder in relation to the bracket which supports my light and heating unit, whereby my line holder can be brought into a horizontal position and the flue it supports into a perpendicular position, regardless of any irregularity present in the contour of the Various parts comprising my bracket and the means I use in mounting my device on to any existing electric fixture.

My invention further consists of novel means for ventilating my heating unit socket to reduce the destructive ali'so1;ptioxi' .o f heat by the socket fromthe unit, thereby prolongmgthe life of the-socket audits various parts, particularly in the case where (chain socket is used and'the controlliiig mechanism loses its efi'ectiveness'becaluse'of tlie' intensity of the heat absorbed hy the sjocl r ji'o'ir'i the heating unit, Q111 liurpos 'l ili fi iwin y -(1 1 .7 gppl ve shev t n these-conv ning draw m'g's thergeo'f ,wlii chjar' Pit; ferredby 1;;nj, smetheyiwill givef'in practice satisfzictory s d tlitmeieg ingjanheugt' fiis to be n r o d h e v in S' l fii tahfiesbtw im "ylih itiqnid i n ct-n5 ver o s ylm n r41 manne s-inane my n n i 'tmi fie the ii i a'r rangement and orgtniz'ation offtheselmtru nientalitiesas herein shogwn' andd'escribedf, I Reta-firingto' the drawingsik-ji"? ;F sqteh selYst sa ip' nines inojunted onlashort' instantiate" s pport lis iit alizi g fishing; sea-dyi washe sl pp'q tieg- 121 k' q tii 'te t hz'ise fiue' flue support hentin unit and-d en hrall ng-q i niif est figure.lqeiiig incl on' on he se tions belliiitttktll 'o'riline. of 2L,-

The various embodiments of my invention disclosed and claimed herein are assembled and controlled so as to give heat or light or both heat and light as desired.
